Be it known that; 'I Buunmm C. SiIPKu NEY, a citizen of the llnited States residm in Elizabeth, in the county of men am State of New Jersey, have invented certain the carbon sheets and the work-sheets, as -the new and useful Improvements in TypewritingMach1nes,

specification.

This invention relates to an improvement in typewriting machines, and more especially to an attachment known asthe an-. fold, for assisting in making anumber of copies of apiece of typewritten work at the same time. 7 r

In this type-of machine, where the work is of a continuous character requirin%y 1a1 number of copies-of the same letter or.

and a large number of letters or bills of similar character, the fan-folded worksheets are fed fi'onzila roll or falls in a pack, with means-for interleaving the work-sheets with carbon sheets: The carbon sheets are'mounted on a traveling table, overwhichthe paper of the work-sheets passes m'contmuous longitudinallyioldecl websor strips, the carbon-- sheets interleaving the work-sheets.

rolls maybe released from theplaten, which enables the operation eta-reversible driv ng connection between a hand crank and the special driving mechanism. for the platenand thetraveling table, whereb the platen may be: reversely rotated-and t e travelmc tablemay be returned, carrying with it both latter are clamped to. the tablefor this movement-.

, The lpackgof sheets is thus withdrawn clear of theiplaten and vthe bend taken: out

so that itj'is straight; thus thework-sheets may be clrawnaronnd the platen alone by i 1 rc'tating'the platen. tospace theinrelatively to the carbon sheets the distance of the aggregate number of lines .of 'writingplus any heading space left at the-top of each sheet or the length of the bill. This. is efi'ectecl by the special driving mechanism which aclvancingly rotates the platen after the feed rolls have b een'QmOVed into. their position,

Fig. 4 is a vertical section from right to left, showing the means for connecting and disconnecting;aznormally silent. pawl, so as to enable the platen and the traveling table to be reversibly driven, thus withdrawing all sheets from the platen. a

Fig.5 is adetail view of the pawl-and ratchet drive, showing the reverse drive pawl as silent, corresponding to the position of the parts in Fig. 4. p

Fig. 6' is an end view in elevation, with parts broken; away to show the underlying structure, and showing the pack comprising the worksheets and carbon sheets as advanced to a osition for the initial line of writing, the cod rolls being in their c1ampin position.

Tig. 7 is a view of the parts shownm B 1g. 6, except that the typewriting action has taken place and a single piece of work or bill has been com leted, so that the carbon sheets and workeets have been advanced the length of the piece of work past the printing point of the typewriter.

Fi 8 is a detail view, similar to the views of Figs. 6 and 7 of the traveling table, showing the same being driven to withdraw reversibly the carbon sheets and work-sheets from the platen just before the traveling table is to be disconnected from the ,drive belt.

Fig. 9 is a view of the parts shown in Fig. 8, just subsequent to the time when the traveling table has come against its stop, so as to disconnect it from the traveling belt, permitting the latter to continue its movement. A latch is shown as having come into engagement with the traveling table to prevent 1ts subsequent return movement for a certain part of the return movement.

Fi 10 is a detail view, similar to Figs. 6 and showing the finish of the reverse drive of the belt subsequent to the position of the parts in Fig. 9, and in which the belt has reached the limit of its reverse drive movement.

Fig. 11 is a view of the parts shown in Fig. 10, the belt, however, having been operated in an advancing or forward feeding direction, so that it has come to a position in which it releases the traveling table, so that the carbon sheets carried thereby can travel with the work-sheets, inasmuch as the latter have been spaced relatively to the carbon sheets by the counter drive of the platen, so as to bring a fresh portion of each worksheet to register with the carbon sheets.

The platen 1 is mounted on an axle 2, which, in turn, is rotatablv mounted on the ty )ewriter carriage 3. he platen 1 is provi ed with the usual Underwood line space mechanism, including a line-space wheel 4 secured to the laten axle 2. To drive the line-space whee 4, so as to advance the platen a line-space at a time, a linespace lever 5 thrusts a slide 6 rearwardly against the tension of a spring.7. The slide 6 has a pawl 8 to engage the line-space wheel 4 at the roper time, so as to rotate the platen 1 a fine-space whose magnitude may be varied as desired.

The usual pressure feed rolls 9 and 10 for clamping the work-sheets with the interleaved carbon sheets to the platen are used. These feed rolls 9 and 10 are mounted on swinging frames 11 and 12 having arms 13 and 14, supported by a rock shaft 15. At the points where the arms 13 and 14 engage the rock shaft 15, the rock shaft is squared so that when it turns, it will spread the arms against the tension of springs 15" Fig. 1, and thus withdraw the feed rolls 9 and 10 from engagement with the work-sheets on the platen, permittin the same to be adjusted relatively to t e platen. The rock shaft 15 is oscillated by a finger-piece or hand lever 16, which is in the form of a bell crank connected by a link 17 to a crank arm 18 provided on the rock shaft 15.

The typewriter carriage has the usual stepby-step movement at the striking of typebars 19 at a Iprinting point20.

The usua line-s ace movement of the platen is augments by a special drive, so that it may be rotated forwardly or backwardly a number of line-spaces at a time for the purpose of properly positioning and removing the work-sheet with respect to the platen. The special drive includes a sprocket wheel 21, engaging a perforated belt 22, which passes over and around a s rocket wheel 23 secured for rotation with the platen 1. This belt 22 passes over guide rollers'or ulleys 24, for a purpose to be mentioned ereafter. y

The driving of the sprocket 21 is done by a hand crank 25, Figs. 4 and 5. .For r0- tating the sprocket wheel 21 in a direction so as to advance the platen in a line-feeding direction, there is provided a s ring-pressed pawl 26, which engages a rate ct wheel 27, secured to the sprocket wheel 21. l/Vhen the hand crank 25 .is rotated in the opposite direction, this pawl 26 will slip idly over the teeth of the ratchet wheel 27.

For rotating the sprocket wheel 21 and thus the platen 1 in the reverse direction, so as to back-feed the work-sheets in a counter line-spacing direction, there is provided a second pawl 28 pivotally mounted on the hand crank 25 and arranged to cooperate with a ratchet wheel 29, secured for rotation with the sprocket wheel 21, but facing in the o posite direction to the ratchet wheel 27. he pawl 28 is normally held out of engagement with the ratchet wheel 29 against a pin 30 by means of a spring 31-.

Y en .it isnecessary to reversibly rotate the platen 1, the pawl 28 is forced into mesh with the ratchet wheel 29. As it is desirable that this action take place when the pressure feed rolls 9 and 10 are withdrawn from their clamping position, the operation of the pawl 28 is controlled from the finger piece 16. For this purpose, there is provided on the pawl 28 a pin 32 which underlies an annular shifter 33 loosely mounted on a shaft 34. The annular. shifter 33 is connected by a link 35 to the finger-piece 16, so that when the latter is shifted to its shifted position, it will also rotate the shifter 33. The shifter 33 is provided with a hub 36 having a notch 37, normally registering with a cam 38 on a fixed hub 39, concenshifter '33, however, will cause the shifter to be cammed to the right, Fig, 4, against the tension of a sprin 40. This action came the in 32 centrlpeta ly so as to force the pawi 28 into engagement with the ratchet wheel 29. The pawl 28 is formed in two parts, the outer engaging nose 41 being plvoted on the body portion, so that if the pawl should hap en tostrike the a ex of one of the teeth 0? the ratchet whee 29, it would yield enough against the tension of a sprm 41" to prevent breakage of the arts an properly set itself subsequently. he ratchet wheels 27 and 29 are secured to the shaft 34, to which the sprocket wheel 21 is also secured, so that whatever ratchet wheel is driven, the sprocket' whe'el Wlll be rotated in a corresponding direction.

The belt 22 drives other mechanism besides the platen 1, but before this mechanism is described, it will be n to explain the arrangement of the wor sheets and carbon sheets. The work-sheets 44, of which there may be several, three being shown may come from a roll or rolls (not shown'l, and extend over a guide-roll 45. The work-sheets 44 may be each of a separate strip, coming from a distinct roll, or V the layers of a single wide strip, foldedover on itself eidewise. The work-sheets 44 extend from the guide-roll 45 overs. traveling table 46 to a second guide-roll 47, and from thence around the platen 1 between the feed-rolls 9 and 10, a paper-apron48' and the platen.

From. the front side of the platen, the work-sheets may extend up through a takeofi 'de frame 49, beneath a cutting-oil knif dfl The knife 50 may be adjusted to any one of aplurality of positions, as best shown in Fi 1. That is to say, the knife blade 50 is agjustably mounted on the guide frame 49 by means of thumb-screws 51, which extend into slots 52 rovided in the frame of the knife-blade. y shifting the knife-blade up or down the length of the work-sheet cut off can be determined. In other. words, this knife-blade forms a gage, and the scalebf the gage includes a reference line 53, whichmay be brought register with anyone of a lurality of reference lines'54', indicated by the numbers 4, 5, 6 and 7, which may be the numbers of difierent forms varying i length. The frame 49 extends up beyon the knife-blade 50 a considerable distance so as to rt the work-sheets, projecting beycndthe ifs-blade 50, before they are severed from thffcontinuous strips.

The table 46, above-mentioned, forms a travelingsuppprt for carbon sheets 5 and 56, whichare located so as to extend between the continuous sheets 44, enabling the type-bars 19 to copy on the under strips of .is rocked shew work-sheets the matter written on the uppermost sheet. For supporting the carbon sheets 55 and 56 there are provided ribs 57 and 58, vertically dis laced relatively to each other and exten in transversely of the traveling table 46. T e table 46 is provided with wheels 59, riding in channels 60 (Fig. 2), in a frame 61 extending rearwardly from the carriage 3 of the typewriting machine. The frame 61 is secured to the carriage 3 by brackets 62, so as to travel-in a letter spacin direction with the y carriage. To support t e frame 61 at'its rear end, it is provided with wheels 68, arranged to travel on astationary rail 64.

As the packof work-sheets and carbon sheets are fed line by line'around the platen;

the table 46 advances toward the platen to permit of the concomitant movement of the carbon-sheet strips and theplaten. To reversely run the traveling table, and thus withdraw the work-sheets and carbon sheets from the platen as a unit, the fin er-piece 16 is operated to concomitantly re ease therolls 9 and 10, and atthe same time connectup the pawl 28 with the ratchet 29. Then thehandcrank 25 is reversely rotated so as to rotate the laten 1 backwardly, and at the same time rive the table 46 backwardly by means of the belt 22. v

For'this latter purpose, there is provided ou the belt 22 a lug 65, which engages one arm 66 of a clam 67, pivotally mounted on a swinging mem er 68, Fig. 7. The other arm 69 of the clamp 67, when the clamp is rocked by the belt 22, grips the bunch of work-sheets 44 between its surface. and a stationary jaw 70. In this way, the worksheets are drawn with the traveling table and the carbon sheets as the table is driven rearwardl by the belt 22.

When t e table reaches the limit of its rearward travel, in Fig. 9, the too 71 on the swinging? mu sUlS comes into engagement with n {1 so that the member 68 is pivot 73, withdrawing the arm 66 of the clamp 67 from engagement with the lug 65 on the drive-belt 22. This permits the drive-belt to be di'iven still arther idly, untilthe lug 65 passes aropnd the pulley 24 and comes into engagement with an abru t stop-pin 74. T1118 warns the operative t at the hmit of drive has been reached, and that the work-sheet stri s and carbon sheets have been entirely with rawn, %l ear18f the platen, to a POSll'IIOII" shown in l The table 46 is locked in its nearmost position! by a sprin -pressed latch 75, so that it cannot return orwardly until the latch is released. This is to prevent the carbon sheets from traveling forward with the work-sheets while the latter are bein advanced to bring a fresh blank portion 51ersof into register with the parbon sheets.

.-, these conditions,

For a return drive of the platen, the release-tinger-piece 16 is returned to normal position, bringing the rolls 9 and 10 in clamping relation with the platen 1. This withdraws the pawl 28 from drivin engagement with the ratchet wheel 29. 1e handcrank 25 may then be rotated to advance the platen in a line-spacing direction. Under these circumstances, the pawl 26 and the ratchet wheel 27 operate.

As the belt 22 turns in the direction of the arrow, of Fig. 11, a lug 76 on the belt 22, just in advance of the pick-up lug 65, engages a cam surface 77 on the swinging member 8 and depresses it against the tension of its spring 78, so AS1130 permit the pick-up lug to escape past the arm 66 of the clamp (37.

l nder these conditions, the traveling table 46 is ready to start forward with the carbon and work-sheets together. At this time the belt 22, by means of a releasing lug 79, disengages the latch from the traveling table 46, leaving it free to move in an advancing direction. Incidentally, the releasing lug T9 is one-way acting and pivotally mounted on the belt- 22, so as to release, when the belt is driven in the direction of the arrow (Fig 11), and pass idly by the latch 75 Wll611 the belt is driven as in Fi". 9. The'latch 75 has requisite camming ant abrupt surfaces, with which the lug is shown in engagement, respectively in Figs. 11 and 9.

The stop 7-1 is adjustable to correspond with the adjustment of the knife-blade 50. It is in the form of a pin mounted on a T shaped arm 82, Figs. 2 and (i. The arm 82 is mounted in a groove in the frame 61.

A clamp pin 83 is screw-threaded so as'to.

enable it to be inserted in and tightened up in any one of a number of holes 83 to hold the arm 82 and thus. the stop pin 74 in any adjusted position.

\Vhen taken with the above. description. the operation \Ve may assume that a set of the work-sheets 44 are properly positioned relatively to the carbon sheets 55 and 56, as in Fig. 6, atthe printing point 20. of the typewriter, ready to start the initial line of writing of a bill or other piece of typewriting work. Under the feed-rolls 9 and 10 will grip the pack of work members closely to the platen 1. The typewriting is doneline by line, inthe usual manner, and the platen ad vanced line by line by means space lever 5. c

\Vhen the sheet is completely written, it will occupy somewhat the )osition of Fig. 7*, with the written sh'ect pro ected in the guide frame 49 above the level of tlie printing point 20. We will assume that considerable of the work-sheet44 has either been written on or projected a .suliicient distance beyond the ends of the carbon sheet, as in Fig. 7 to of. the line will be readily understood.

' bon sheets carried mg brought to ahalt by ermit a, considerable backward movement of the platen 1 and thework-sheets without the work-sheets entirely leaving the platen.

The platen rolls 9 and 10 are now released by an actuation of the fin er-piece 16, so that the work-sheets andcar on sheets can be drawn rearwardly from the laten as a unit. This action, as explained a ove, forces the normally disconnected pawl 28 into mesh with the ratchetwheel29. The hand-crank 25 can now be rotated reversely, that is, in a direction to rotate the platen 1 backwardly.

The backward movement of the belt 22 brin s the lug (i5 snugly against the arm 66, ig. 7, so as to force'the clamp 67 to grip the work-sheet strips 4 1, forcing the table 46 to carry them rearwardly. The clamp 67, it willbe noted, forms one ele-' ment of a clutch which connects the table 46. in trailing relation with the belt 22. Inas- 85 much as t e carbon sheets55 and .56 are fixed on the table 46, they will travel with the table and with the work-sheet strips. The movement is continued until the carbon sheets and the written portion of the worksheet in juxtaposition to the carbon sheet are entirely withdrawn from the platen 1, and preferably to such a distance as to get beyond the kink or bend in the pack of sheets, as in Fig. 10, so as to avoid friction between the carbon sheets and the worksheets in subsequent relative feeding movements.

At this time, the toe 71 on the swinging member 68 is rocked to disconnect the travcling table 46 from the belt 22. This ermits the clamp 67 to release the works eet strips 44. At the same time the latch 75 comes into play, as in Figs. 9 and 10, thus locking the traveling table 46 and the cal thereby from an advancmovement. The belt 22 drives the stop 74.

The pressure rolls 9 and 10 may now'be brought into intimate contact with the worksheet stri )S 44, so as to bindthem on the platen. his action withdraws the pawl 28 to an idle position, thus'jdisconnecting the reverse drive, The pawl 26, however, is i mesh with the ratchet wheel 27, so. that the crank 25 may now be rotated in an advancing direction to rotate the platen in a line:

on until spacing direction.

I Fig; 6, with'the tops of the rbon sheets and bringing fresh portions .0 the work-sheet strips into opposition to the carbon sheets, so as to collate them for new typewriting. The table 46 is heldstationary by the latch 7 5 up to this time.

When the relative shift of the sheets has been accom lished, a continued movement of the ban -crank 25 causes the lug 76 to earn the swinging member 68 to such a position as to permit theconnecting lug 65 to conic in front of theclamp 67. At the same time the releasing In '79 unlocks the travel: ing table 4:6 from t e latch 75. Nowthe carbon sheets and the traveling table ad Vance with the work-sheets until they come around to a position, somewhat like that of carbon sheets just beyond the initial line to be written on, and-"this line of the work-sheets will be atthe printing point 20 of the typewriter. This will be the finishin point of the movement of the hand-cran 25. The bill or-piece of wdrk just previously written will project from a point beyond the printing point 20 to the edge of the knife-blade 50, as indicated at 80. The second removed bill or piece of work to be written will have been advanced beyond the knife-blade 50, as at 81, and may be cut OK at this time. It will be seen that it is necessary to leave the previously written bill or piece of work in the machine to allow for the next with drawing and advancing movement, to ive work or .and carbon sheets withdrawn,

a relative displacement between the car on sheets and the work-sheet strips.

Under these circumstances, the partd'are in a position to typewrite the next piece of bill. The only pawl connecting the sprocket wheel 21 is pawl 26, and, inasmuch as the sprocket wheel 21 is rotated in an advancing direction, the crank 25 may move idly with the ratchet wheel or may click over the ratchet teeth idly'when the platen is line-spaced. The table 4d keeps ace with the line-space movements of the p aten and advances until the last line is written of the piece of work or bill. Witha new bill written, the feed rolls are released and the work displaced and returned to the platen as before.

Variations may be resorted to within the scope of the invention, and portions of the imlplrovements may be used without others.
